In this brief educational clip, the speaker outlines the two primary types of sleep—non‑REM (the body's physical rest) and REM (the mind's mental rest). They emphasize that sleep also involves a third component: the body's connection to the external environment via the circadian rhythm, which is driven by the sun. The speaker explains how light exposure triggers biochemical responses, notably the production of melatonin, which is low during daylight and rises at night to promote sleep.
